7.1 Overview

The AM275x processor from the Signal Processing Microcontroller family is targeted for audio applications needing high-performance Digital Signal Processing.

Key cores on the device include the ARM® Cortex®-R5F and C7000™ (“C7x”) scalar and vector DSP core from Texas Instruments, a dedicated Matrix Multiplication Accelerator (MMA), and Asynchronous Audio Sample Rate Converters (ASRC). All protected by automotive grade safety and security hardware accelerators.

DSP Core Overview: the C7x core provides up to 40GFLOPS of DSP compute. It achieves 4x to 8x or more performance compared to the previous generation C66x DSP core. Some of the key features includes:

  • 256-bit fixed- and floating-point DSP vector core
  • Single-cycle latency to access L2 memory via Streaming Engine
  • Improved control code efficiency
  • True 64-bit machine with 64-bit memory addressing and single-cycle 64-bit base arithmetic operations

Integration Overview: along with dual C7x DSP cores, the AM275 SoC integrates up to Quad Arm® Cortex®-R5F cores capable of running in dual lockstep mode or all independently. Integrated diagnostics and safety features support operations up to ASIL-B levels while the integrated security features protect data against modern day attacks. The AM275 device also offers a 2-port Gigabit Ethernet switch with Time-Sensitive Networking (TSN) to enable audio networking features such as Ethernet Audio Video Bridging (eAVB), while peripherals like the McASP enable multi-channel I2S and TDM Audio inputs and outputs. The device also includes two hardware Asynchronous Audio Sample Rate Converters (ASRCs) to convert audio sample rates on digital audio streams.
